How to Choose a Hose for Your Portable Air Conditioner

Before buying a portable AC hose, we recommend you consider a few factors. Of course, choosing the right one for the given air conditioner BTU is a no-brainer. Still, installation, convenience, and maintenance are also essential.

Single or Dual Hose Design

While single hose ACs are a spread choice due to their price, dual hose designs are more efficient.

The former draws warm air in, cools it, and pushes the ready air back to the room. The warm particles and moisture are expelled through the exhaust hose and the drainage pipe. This solution has no space to draw more air, creating “negative air pressure” inside the room.

Consequently, warm air will creep in through the door, window, and other cracks in the building structure. When this happens, the efficiency of your unit decreases.

On the other hand, dual hose units draw a controlled amount of air from outside through the second hose to cool down the appliance. As a result, the AC experiences less strain during cooling and serves longer.

Exhaust Hose Size and Length

A standard exhaust hose is somewhere from 5 to 7ft long and made out of high-quality plastic. You can use longer hoses too. However, experts don’t advise having it longer than 12ft, as it can bend and move. Plus, the AC exhaust force might not be able to push out the residue air.

Another aspect to consider is the bend angles. If the bends at 90 degrees anywhere on the length, the AC might stop working, as the moisture won’t escape.

As to the size of the hose, it should be around 5″ or more. Anything smaller won’t work.

Installation and Maintenance

The best portable air conditioning units are small and convenient. They should be easy to install, remove, and repair. The user should be able to use them in different rooms with no difficulty. Thus, hose installation and removal need to be as simple as possible.

As you might already know, your AC creates hot air exhaust. Cooling also results in dehumidification and condensate production.

Most air conditioners gather the drainage water in a container inside the unit. There are several methods to get rid of it. You can drain it into a pan, bathtub, or sink. Still, if you want to avoid a manual process, connecting a hose is also a valid option.

Once attached, the product will drip the water into the drainage system of your house without you even knowing it. While this method is convenient, it also takes away from the portability of the air conditioner.

LBG Products PVC drain pipe is a product that will serve its purpose without extra effort.

Bottom Line

Use LBG pipe to get rid of the condensate water from your portable AC without needing a manual drainage process. This flexible PVC hose is easy to install and adjustable.

Its end sizes allow you to connect two similar pipes. Thus, you can easily adjust its length to reach the drainage system. The only thing you need to ensure is that the hose tilts downwards for easy water flow. Otherwise, the AC might malfunction.

Types of Hoses for Portable ACs

Portable ACs use two types of hoses. One is for exhaust, and the other is for drainage. These differ in materials used, length, and flexibility. While exhaust hoses are built to handle hot air, drainage pipes are adapted for carrying water.

Exhaust Hoses

These hoses carry the hot air out of your AC through the window. These pipes are made from polypropylene and use metallic threading inside to help the airflow. Besides, the latter makes it easy to extend and shrink.

This benefits not only everyday use but also ensures secure storage.

The best exhaust hoses are wide, lightweight, flexible, and durable. Replacement hoses don’t usually come with connection couplers, so we recommend you check two things before buying:

  • The rotation direction of the threading
  • If the pipe comes with couplers

Drainage Pipes

Some AC models drain residue moisture through openings on the back of the appliance. The original manufacturers might not include these pipes in the box because it’s easy to empty the AC drainage by removing the plugs and tilting the device.

However, some users prefer connecting the air conditioner to the mainline to avoid extra work.

These pipes are usually narrow and made from flexible yet sturdy plastic. Often, they’re insulated to help the system avoid double condensation.

What’s the Difference Between a Dual Hose vs Single Hose?

Although both types serve the same purpose of cooling the air, single and dual hose air conditioners are quite different in the technology they use to achieve the final goal. Below, we discuss the most crucial aspects you should consider while choosing one of these options.

Air Control

Single hose units draw the air from the room, creating “negative pressure” as they give back only the part of the air it drew in. As a result, hot air finds ways to get into the room through various cracks in the building and around the windows.

This gives the unit less control over the airflows. On the other hand, dual hose ACs draw additional air through the second pipe, making the exchange more natural.

Most of these AC units also act as air purifiers and dehumidifiers, filtering and improving the indoor air quality.


Single and dual hose air conditioning units of similar tonnage (BTUs) have different efficiency in the same area. The former work much harder than the latter to the same effect. Although single hose ACs use less electricity, they cool the same room less efficiently than a dual option with the same BTUs.


Dual hose ACs are pricey, but if you want better cooling and more power from your machine, choosing them might be the better decision.


Quality exhaust and drainage hoses are essential for your portable AC. You don’t have to settle for low quality when the original one breaks or tears. Use our guide to find the best one for your appliance and extend its service time. 

People Also Ask

Our article might’ve already answered your basic questions about the best portable AC hose types and brands. Still, let’s review the most frequently asked ones to ensure we haven’t missed anything important. 

How Long is the Exhaust Hose That Portable Air Conditioners Come With?

Portable ACs come with a hose of 5 to 7ft. However, you can easily find and replace them with a longer one (up to 12ft is the advisable length). The bends should also be gentle (more than 90 degrees) because the unit might struggle to push the air and moisture out.

Can I Extend the Exhaust Hose for My Portable Air Conditioner?

Technically, yes.

However, extending the hose might cause an efficiency drop. Usually, the hose that comes in the package is of the specific size that will help the unit operate at its peak. While you can stretch it to its maximum length, keeping it in the shortest possible one is recommended.

What Do the Hoses on a Portable AC Do?

During operation, portable AC units take the air in, send it through the coils, and then return it back to the room. During the process, it generates heat, simultaneously drawing the moisture out of the air. The hose aims to move the exhaust (warm air and water droplets) out of the AC unit.

Can You Use a Dryer Vent Hose for a Portable Air Conditioner?

The manufacturers don’t recommend it. However, it’s possible if you look for the right size (5″ and larger). You should also get rid of the flaps on the outer part of the dryer vent. The AC’s compressor might not be strong enough to open the flaps.
